However, today, many publishers are moving away from dialogue tags as this is more telling than showing. Adding an action beat for whoever is talking is a way to show that person is the one talking instead of saying so-in-such said.
As a reader, to be honest, I never really noticed that kind of stuff and it never bothered me. But now as a writer as I sit reading a book, if I see a whole bunch of unnecessary dialogue tags it almost makes me want to stop reading the book. I get through it, especially if I’ve paid for it, but I know that it could have been written a whole lot better without them. For me this shows that I’ve grown as a writer and know that I’m improving over time.
Then here recently I won in an auction some time with an author who has many books published. Guess what she told me to add to my story in many places instead of how I had it? If you guessed ‘so-in-such said’ you’d be right. I was kind of dumbfounded by this, but I figure if she has well over 50 books published she might know what she’s talking about. I guess you could call it just more food for thought. It just goes to show you there are never any 100% rules in writing. In the end, go with your gut and what you feel is best for your story.
